Re: for loop over parameter expansion of array can miss resulted empty list

[Alexey via Bug reports for the GNU Bourne Again SHell]

I can add one more example, which change array size while it's not 
expected behavior:
x=("/"); y=("${x[@]%/}"); echo "x size: ${#x[@]}, y size: ${#y[@]}"
Goal of this example show that it is not only for loop issue.
